Question

我编写了一个PowerShell脚本，用于将新文件复制到服务器上的共享文件夹中。

我想知道是否有办法在我获得子文件夹中的新文件列表后，我可以将它们一起复制 - 除了使用for-each并一次复制一个 - 这样我就可以添加进度条。

这样的事情可能是一个起点

# define source and destination folders
$source = 'C:\temp\music'
$dest = 'C:\temp\new'

# get all files in source (not empty directories)
$files = Get-ChildItem $source -Recurse -File

$index = 0
$total = $files.Count
$starttime = $lasttime = Get-Date
$results = $files | % {
    $index++
    $currtime = (Get-Date) - $starttime
    $avg = $currtime.TotalSeconds / $index
    $last = ((Get-Date) - $lasttime).TotalSeconds
    $left = $total - $index
    $WrPrgParam = @{
        Activity = (
            "Copying files $(Get-Date -f s)",
            "Total: $($currtime -replace '\..*')",
            "Avg: $('{0:N2}' -f $avg)",
            "Last: $('{0:N2}' -f $last)",
            "ETA: $('{0:N2}' -f ($avg * $left / 60))",
            "min ($([string](Get-Date).AddSeconds($avg*$left) -replace '^.* '))"
        ) -join ' '
        Status = "$index of $total ($left left) [$('{0:N2}' -f ($index / $total * 100))%]"
        CurrentOperation = "File: $_"
        PercentComplete = ($index/$total)*100
    }
    Write-Progress @WrPrgParam
    $lasttime = Get-Date

    # build destination path for this file
    $destdir = Join-Path $dest $($(Split-Path $_.fullname) -replace [regex]::Escape($source))

    # if it doesn't exist, create it
    if (!(Test-Path $destdir)) {
        $null = md $destdir
    }

    # if the file.txt already exists, rename it to file-1.txt and so on
    $num = 1
    $base = $_.basename
    $ext = $_.extension
    $newname = Join-Path $destdir "$base$ext"
    while (Test-Path $newname) {
        $newname = Join-Path $destdir "$base-$num$ext"
        $num++
    }

    # log the source and destination files to the $results variable
    Write-Output $([pscustomobject]@{
        SourceFile = $_.fullname
        DestFile = $newname
    })

    # finally, copy the file to its new location
    copy $_.fullname $newname
}

# export a list of source files
$results | Export-Csv c:\temp\copylog.csv -NoTypeInformation

注意：无论大小如何，都会显示总文件的进度。例如：你有2个文件，一个是1 mb，另一个是50 mb。复制第一个文件时，进度将为50％，因为复制了一半文件。如果你想要总字节数的进展，我强烈建议尝试这个功能。只是给它一个来源和目的地。给定单个文件或整个文件夹进行复制时可以正常工作
